IMPROVEMENT IN COOKING-STOVES.

Specification forming part of Letters Patent No. 118,534, dated August29, 1871.

To all whom it may concern:

Be it known that I, GEORGE E. HOPKIN, of the city of Philadelphia, inthe State of Pennsylvania, have invented certain improvements in theapplication of hot-Water tanks to stoves, of which the following is aspecification:

My invention relates to the application to the top plate of acooking-stove of a water-heating tank, in such ahnanner that the hotproducts of combustion which usually escape from the stove to thechimney will be compelled to pass in contact with the whole surface ofthe bottom and one side of the tank before they reach the chimney; andthis I accomplish by the attachment of an open case provided withpartitions, an opening in its bottom for the insertion of the outsideflanch of the exit-flue of the stove, and a flanched opening in the topof the case for the usual chimney-pipe, in such a manner that when the.watertank is applied to the said open case the usual hot waste productsof combustion will pass in contact with the bottom and one side of thetank, as before stated 5 the object of my invention being the productionof a water-tank, applicable to any of the cooking-stoves in use, thatwill be heated in the manner stated by the usual waste heat'on itspassage to the chimney.

Figure 1 is a perspective view ofthe open case for receiving theWater-tank, the front plate at the bottom being removed. Fig. 2 isan'end elf evation of the open case with the Water-tank applied thereto.

The open case A is closed at its top and bottom, and partly at its endsand front, so as to leave an open space in front for the reception of anoblong rectangular Water-tank, B, which Will accurately t and close thesaid open space. (See Fig. 2.) The interior of the caseAis divided bytwo vertical partitions, a a, and one horizontal partition, a", whichconnects with the extreme upper ends of the vertical partitions a a, allin such a manner that when the tankl B is applied the case Will bedivided into a middle flue, 4, communicating with two end ilues, 5 5,and a horizontal flue, 6, above the middle ue. The middle of the rearside of the case has a semicircular projection, 7, in the plate for thetwofold purpose of affording room for an opening, 8, in

It will be understood, without further descrip A tion, that the case A,with its water-tank B applied as in Fig. 2, is to be placed on the backpart of the top plate of the stove, and the 'case bolted or otherwisesecurely fastened and supported upon the plate, with the lanched end ofthe exit-flue of the stove inserted in the hole 8, the dotted lines V W,Fig. 2, indicating, respectively, the back and top plates of the stove.It will also be understood that the draught through the iues in the caseA will be substantially in the direction indicated by the arrows shownin Fig. l, and that the whole outward surface ot the bottom and one sideof the water-tank B will be exposed to the heat of the draught, and theWater of the tank kept proportionately heated.

I claim as my invention- The construction and arrangement of the case Aand the water-tank B in relation to each other and to any suitablestove, whereby the escapeue draught on its way to the chimney passesoutside ofthe tank B and in direct contact with the whole surface of thebottom and one side of the same, substantially as and for the purposehereinbefore set forth and described.
